摘要
大连小平岛假日公寓主塔大屋面高度269.0m,属超限高层结构。主楼平面呈十字形,属平面不规则结构。在水平地震作用下,连接部位楼板要承受较大水平剪力。在初步设计阶段采用两种常用方法对楼板承担的剪力进行估算,并且推导出一种剪力估算新方法:位移差法。通过与PMSAP计算结果对比得出:位移差法计算结果与PMSAP计算结果较为接近。位移差法概念清晰、易于操作,在初步设计阶段使用该方法,可以较为准确的得到楼板的面内剪应力。
The super high-rise holiday apartment in Dalian Xiaoping island is 269 meters height,In addition,the structural plan presents crisscross,and this form belongs to irregular structure.Large horizontal shear stress occurs at the connected position under the horizontal seismic force.Designers adopt two methods to estimate the shear force at the stage of the initial design,as a result,a new method to estimate the shear force is developed and it is called displacement difference method. The comparison between the new method and the PMSAP method is made and the results of two methods is comparable. The concept of the displacement difference method is easy and it can be used in the initial design stage,the accurate results can be derived by this method.
